由于膜过滤技术具有分离效率高、节能、设备简单、操作方便等优点, 使其在废水处理领域有很大的发展潜力。但由于工业废水往往含有酸、碱、油等物质, 处理条件比较苛刻, 因此, 处理废水使用的膜必须具有较好的材料性能, 从而在苛刻的条件下保持良好的分离性能和较长的使用寿命。从这方面来看,开发抗污染等性能优良的过滤膜具有重要的战略意义。由于工业废水的复杂性, 任何单一技术的处理往往达不到理想的效果, 必须重视膜分离技术与其他水处理技术的集成工艺研究, 发挥各种技术的优势,形成废水深度处理的新工艺。
Because of its advantages of high separation efficiency, energy saving, simple equipment and convenient operation, membrane filtration technology has great development potential in the field of wastewater treatment. However, industrial wastewater often contains acid, alkali, oil and other substances, and the treatment conditions are relatively harsh. Therefore, the membrane used for wastewater treatment must have good material properties, so as to maintain good separation performance and long service life under harsh conditions. From this point of view, it is of great strategic significance to develop filter membranes with excellent anti pollution performance. Due to the complexity of industrial wastewater, any single technology can not achieve the desired results. It is necessary to pay attention to the integrated process research of membrane separation technology and other water treatment technologies, give full play to the advantages of various technologies, and form a new advanced wastewater treatment process.
